Being big may be our problem

I’ve been having some amazing things click lately. If there is alien life in the universe, why haven’t we detected it? Why haven’t they contacted us? I think they are here, including inside of us.

Imagine that we are trying to work out how to move to other planets and how to live for millions of years. Now consider that the entire genetic blueprint for a human would fit inside an organism the size of a bacteria. A human egg cell is about the diameter of a human hair, 100 microns, but a human sperm head is about 5 microns. That sperm cell head at 5 microns contains all the genetic code of a complete intelligent adult human. Also in the range of .2 to 5 microns: Bacteria.

My idea is that a very advanced alien race could have invented the first bacteria that arrived on earth as a way to transport themselves to another world. Bacteria, which can live in space, survive radiation and near zero temperatures and can survive dormant as spores for 25 million years, repair their DNA and reproduce, would be like alien super sperm. Under the right conditions, as does a 5 micron human sperm cell, they grow into some large intelligent life form, perhaps the Grey aliens in the movies, or something with a form best adapted to the current environment.

Bacteria share genetic information (they learn) so we may just be in the phase where they are learning the best traits of life on this planet before they germinate into a new creature that takes over the planet.

Next step: I’d like a look at the genetic code of the oldest bacteria we’ve found.

NASA’s Landsat Satellites See Dalhart Texas Crop Circles 1972 to 2011

A water-rich polka dot pattern takes over the traditional rectangular patchwork of fields in this time series animation of 40 years of Landsat images. In the dry Texas panhandle near the town of Dalhart, this transformation is due to center-pivot irrigation, a farming method that improves water distribution to fields. It was invented by farmer Frank Zybach in 1949.

Center-pivot irrigation works by pumping water from the center of the field through a long pipe that rotates above growing crops like the hand of a clock. Evenly spaced sprinklers along the pipe deliver water with minimal loss to evaporation. Farmers like center-pivot irrigation because it works with a variety of soil types and it can be used on slopes where other gravity-driven forms of irrigation cannot.

As it caught on in the United States and abroad, it revolutionized agriculture since the system can be adapted to a wide variety of terrains and is more efficient with water and labor than other forms of irrigation. Together, all types of irrigation water 20 percent of cultivated fields worldwide, and those fields produce about 40 percent of the global food supply.

In this time series animation, vegetation appears red and the bare soil of fallow fields or sparsely vegetated grasslands appear white to green. The blue-gray X near the center of the images marks the town of Dalhart.

This series uses data from four Landsat satellites. Shown in this false color composite is light reflected from the near-infrared, red, and green regions of the electromagnetic spectrum (bands 4, 2, and 1 from the Multispectral Scanner Systems (MSS) aboard Landsat 1, 2, and 4, and bands 4, 3, and 2 from the Thematic Mapper (TM) aboard Landsat 5).

The Landsat satellites have provided scientific data on Earth’s land surfaces for the past 40 years: Landsat 1 from 1972 to 1978; Landsat 2 from 1975 to 1982; Landsat 3 from 1978 to 1983; Landsat 4 from 1982 to 1993; and Landsat 5 for a record-breaking 28 years from 1984 to what was likely its last data downlink in 2011.

Currently, Landsat 7, launched in 1999 is still providing data. The data from Landsat satellites has been instrumental in increasing our understanding of forest health, storm damage, agricultural trends, urban growth, and many other ongoing changes to our land.

NASA and the U.S. Department of the Interior through the U.S. Geological Survey (USGS) jointly manage Landsat, and the USGS preserves a 40-year archive of Landsat images that is freely available data over the Internet.

The next Landsat satellite, now known as the Landsat Data Continuity Mission (LDCM) and later to be called Landsat 8, is scheduled for launch in January 2013.

Berries keep your brain sharp

Berries are good for you, that’s no secret. But can strawberries and blueberries actually keep your brain sharp in old age? A new study by researchers at Brigham and Women’s Hospital (BWH) finds that a high intake of flavonoid rich berries, such as strawberries and blueberries, over time, can delay memory decline in older women by 2.5 years. This study is published by Annals of Neurology, a journal of the American Neurological Association and Child Neurology Society, on April 26, 2012.

“What makes our study unique is the amount of data we analyzed over such a long period of time. No other berry study has been conducted on such a large scale,” explained Elizabeth Devore, a researcher in the Channing Laboratory at BWH, who is the lead author on this study. “Among women who consumed 2 or more servings of strawberries and blueberries each week we saw a modest reduction in memory decline. This effect appears to be attainable with relatively simple dietary modifications.”

The research team used data from the Nurses’ Health Study—a cohort of 121,700 female, registered nurses between the ages of 30 and 55—who completed health and lifestyle questionnaires beginning in 1976. Since 1980, participants were surveyed every four years regarding their frequency of food consumption. Between 1995 and 2001, memory was measured in 16,010 subjects over the age of 70 years, at 2-year intervals. Women included in the present study had a mean age of 74 and mean body mass index of 26.

Findings show that increased consumption of blueberries and strawberries was associated with a slower rate of memory decline in older women. A greater intake of anthocyanidins and total flavonoids was also associated with reduced memory decline. Researchers observed that women who had higher berry intake had delayed memory decline by up to 2.5 years.

“We provide the first epidemiologic evidence that berries appear to slow progression of memory decline in elderly women,” notes Dr. Devore. “Our findings have significant public health implications as increasing berry intake is a fairly simple dietary modification to reduce memory decline in older adults.”

Learning mechanism of the adult brain revealed

They say you can’t teach an old dog new tricks. Fortunately, this is not always true. Researchers at the Netherlands Institute for Neuroscience (NIN-KNAW) have now discovered how the adult brain can adapt to new situations. The Dutch researchers’ findings are published on Wednesday in the prestigious journal ‘Neuron’. Their study may be significant in the treatment of neurodevelopmental disorders such as epilepsy, autism and schizophrenia.

Our brain processes information in complex networks of nerve cells. The cells communicate and excite one another through special connections, called synapses. Young brains are capable of forming many new synapses, and they are consequently better at learning new things. That is why we acquire vital skills – walking, talking, hearing and seeing – early on in life. The adult brain stabilises the synapses so that we can use what we have learned in childhood for the rest of our lives.

Earlier research found that approximately one fifth of the synapses in the brain inhibit rather than excite other nerve-cell activity. Neuroscientists have now shown that many of these inhibitory synapses disappear if the adult brain is forced to learn new skills. …

Green clouds over Moscow spark disaster fears

Mysterious green clouds have been spotted over the Russian capital, sparking fears of a chemical disaster and even some doomsday theories.

­But the Emergencies Ministry is advising the public to calm down. It says the clouds are actually composed of birch pollen, not of chemicals from an allegedly burning factory in the Moscow region, as some reported.

Some people, however, got so scared that even the official comments could not convince them. Russian Twitter users have been posting alarming messages like “Moscow schools are closed because of the blast! Children are sent home,” “Sky has turned completely green in Moscow’s south!” and “The factory in Kaluga is destroyed!” A flood of 911 calls was also registered.

Others believe that the authorities are hiding information from the public: “Pollen is just an excuse. It might as well be the beginning of the Apocalypse!” one popular Russian blogger posted to his readers.

The odd natural phenomenon mystically coincided with the 26th anniversary of the Chernobyl disaster, which caused further speculation about the authorities withholding information.

Biologists say birch trees started blooming yesterday, which would also explain why Muscovites have started sneezing. Birch pollen is a strong allergen, so people suffering from hay fever are strongly advised to take the necessary steps.

“This pollen can stay in the air for quite a long time – around four weeks,” biologist Vladimir Murashov told Ria-Novosti. “The wind can carry it ten kilometers from the tree.”

Curious NASA Photo Stirs Debate

According to Life’s Little Mysteries, a scientist at the Naval Research Laboratory, or NRL, theorizes the object in space is just a collection of streaks left by cosmic rays that hit the camera’s CCD sensor.

“The streaks in question are consistent with energetic particle (proton) impacts on the CCD, something which is apparent in just about every image,” Nathan Rich, of the NRL’s solar physics branch, told the website.

“These artifacts do not persist from image to image,” Rich added, which suggests the cosmic streaks can explain what UFO proponents are hoping turns out to be an extraterrestrial craft.

A cosmic ray burst on the camera may also account for the “boom arm,” pictured below, that seems to be attached to the hinged “spacecraft.”

Bullet-in-head titleholder dies at 103

The man who held the Guinness World Record for living the longest with a bullet in his head has died at age 103.

The Modesto Bee newspaper reports that William Lawlis Pace died in his sleep at a California nursing home on Monday – 94 and a half years after his older brother accidentally shot him with their father’s .22 calibre rifle in 1917.

Pace learned he had been crowned the world record holder in the category of unwanted cranial ammunition acquisition in 2006.

His son told a newspaper last year that doctors in Pace’s native Texas left the bullet in place because they worried that surgery might cause brain damage.

The injury damaged one of his eyes but did not prevent Pace from working as a cemetery custodian.

Idaho man accused of using gun to force ‘moonwalk’ – Yahoo! News

An Idaho man has been charged with assault after authorities say he ordered another man to perform the “moonwalk” at gunpoint.

The Bonner County Daily Bee (http://bit.ly/IGAoPn) reports 30-year-old John Ernest Cross was charged with the felony Tuesday in 1st District Court and appointed a public defender.

Police say they were called Monday to Cross’ home in Clark Fork after getting a report that he pointed a rifle at another man and demanded that the man perform the dance move popularized by Michael Jackson in the 1980s.

Investigators accuse Cross of using a semiautomatic rifle during the episode, but Cross claimed during his initial court appearance this week that the firearm was simply a pellet gun.

Jellyfish-Like Organisms Shut Down California Power Plant

The workers of the Diablo Canyon nuclear power plant received a very slimy surprise this week when they discovered hoards of jellyfish-like creatures clinging to the structure, leading to the shutdown of the plant.

The organisms, called salp, are small sea creatures with a consistency similar to jellyfish.

The influx of salp was discovered as part of the plant’s routine monitoring system, according to Tom Cuddy, the senior manager of external and nuclear communications for the plant’s operator, Pacific Gas & Electric.

“We then made the conservative decision to ramp down the affected unit to 20 percent and continued to monitor the situation,” Cuddy said. “When the problem continued, we made another conservative decision that it would be safest to curtail the power of the unit.”

The salp were clogging the traveling screens in the intake structure, which are meant to keep marine life out and to keep the unit cool.

“Safety is the highest priority,” Cuddy said. “We will not restart the unit until the salp moves on and conditions improve. No priority is more important than the safe operation of our facility.”

The plant consists of two units. Unit 1 was shut down previously because of refueling and maintenance work and will not be functional for several weeks. Now that Unit 2 has been shut down because of the influx of salp, the plant has ceased all production.

Even with the Diablo Canyon plant out of commission, PG&E has pledged to continue production using other sources of power so that customers are unaffected by the closure.

“We’ve had salp cling to the intake structure before, but nothing to this extent,” Cuddy said.

The plant’s strategy? Simply wait until the salp move on and resume production once the filters are clear.

Huge “Snowballs” Seen Piercing Saturn’s Outer Ring

Giant “snowballs” have been discovered plunging through Saturn’s outermost ring, creating glittering trails of ice dubbed mini-jets, researchers have announced.

The jets were uncovered in new images from NASA’s Cassini orbiter, which has been touring the Saturnian system for the past seven years.

The colliding snowballs are formed as material in Saturn’s F ring coalesces due to the gravitational pull of the nearby moon Prometheus. Scientists estimate that the icy bodies, including the one seen above, are each about 0.62 mile (a kilometer) wide.

Sometimes a snowball sails back through the F ring at a gentle clip of roughly 4 miles (6.4 kilometers) an hour, dragging along icy particles.

The resulting jets “are about 10 kilometers [6.2 miles] wide and extend out from the rings anywhere from 40 to 180 kilometers [25 to 112 miles], depending on their age, with their lengths increasing dramatically over just a few hours,” said Carl Murray, a Cassini imaging team member based at Queen Mary University in London, England.

“At any given time we might expect to see about ten of these if we looked all the way around the F ring.”

—Andrew Fazekas

. …

Using pictures from Cassini’s narrow-angle camera, scientists were able to track the snowballs at the ends of the mini-jets, such as the one above, as they plowed through Saturn’s F ring.

“We have yet to obtain resolved images of these objects,” Murray said.

“However, when we see an obvious ‘head’ at the end of the mini-jet trail, it tends to have a fuzzy appearance”—suggestive of the halo that surrounds a comet—”produced, perhaps, from material on its surface or F ring core material.”
